These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
- One of the key factors that determine the performance of a piston oil seal is its compatibility with the engine's oil
The oil seal should be tough enough to withstand the pressure and the vibrations caused by the shaft and bore. Check if the oil seal is strong enough to tolerate the pressure and vibration.

Nitrile Oil Seals - Nitrile oil seals, which is the commonly used term for acrylonitrile-butadiene rubber seals, is a very good general-purpose option due to the flexibility of use across a variety of components. The resistance is strong against fats, hot water, gasoline, mineral oils, grease and animal oils, making them the most often-used oil seals. They do not have a wide temperature range, making them a poor choice for machinery that can see extreme changes in temperature.
The head gasket and valve cover gasket are critical components in the engine's sealing system. The head gasket seals the cylinder head to the engine block, while the valve cover gasket seals the valve cover to the cylinder head. Both gaskets play pivotal roles in maintaining the integrity and functionality of the engine, preventing oil leaks and ensuring the proper sealing of the combustion chamber.

Oil seals come in a wide range of types, and they also have various sizes.
When selecting the right oil seal for your machine from among these many varied types of oil seals, the following two criteria are very important.

Metal cased design
These oil seals are the best for applications involving high temperatures. It’s suitable for temperatures between -4 degrees Fahrenheit and 392 degrees Fahrenheit. Also, it’s highly resistant to acids, dissolvent materials, and other chemicals. Viton (FKM/FPM) oil seals can run at a maximum speed of 38 m/s.
Which option is best? This decision is left entirely to you. Whatever solution you choose, the seal needs a proper fit to function.
Silicone Oil Seals - Designed to absorb lubricants in order to lessen wear and friction, silicone rotary shafts also offer high thermal resistance and a large temperature range. But, they do not handle abrasions well or interact with oxidized oils.
